Introduction The Cisco IOS XR software is a distributed operating system designed for continuous system operation combined with service flexibility and speed. The following is a high-level overview of Cisco IOS XR software features and benefits: • IP and Routing—Supports a wide range of IPv4 and IPv6 services, and routing protocols; including Border Gateway Protocol (BGP), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, Routing Policy Language (RPL), and Hot Standby Router Protocol (HSRP)/Virtual Router Redundancy Protocol features (VRRP). • MPLS—Supports Multiprotocol Label Switching (MPLS) protocols such as Traffic Engineering (TE), Resource Reservation Protocol (RSVP), and Label Distribution Protocol (LDP). • Multicast—Provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Bidirectional Protocol Independent Multicast (BIDIR-PIM) support. • Quality of service (QoS)—Supports rich QoS mechanisms including classifying, policing, marking, queuing, and shaping. The operating system supports the Modular QoS CLI (MQC), a consistent API that is used to configure QoS features on Cisco routing platforms. • Manageability—Provides industry-standard management interfaces including modular command-line interface (CLI), Simple Network Management Protocol (SNMP), and native Extensible Markup Language (XML) interfaces. • Security—Provides comprehensive network security features including access control lists (ACLs), routing authentications, AAA/TACACS+, Secure Shell (SSH), SNMPv3, and leading Routing Policy Language (RPL) support. Control plane protections integrated into line card ASICs include Generalized TTL Security Mechanism (GTSM), RFC 3682, and dynamic control plane protection. • The Craft Works Interface (CWI)— A client-side application used to configure and manage Cisco routers. The management and configuration features include fault, configuration, security, and inventory, with an emphasis on speed and efficiency. The CWI provides a context-sensitive graphical representation of the objects in a Cisco router, simplifying the process of configuring and managing the router. The CWI allows you to log in to multiple routers and perform management tasks. • Partitioning into Secure Domain Router (SDR)—A logical router is a set of line cards and route processors (RPs) that form a complete router. More specifically, each SDR contains its own instance of dynamic routing, IP stack, SysDB (system database), interface manager, event notification system, and so on. • Availability—Supports rich availability features such as fault containment, fault tolerance, fast switchover, link aggregation, and nonstop forwarding (NSF). Cisco IOS XR Supported Platforms and Features 2 OL-8505-01 Cisco IOS XR Supported Platforms and Features Platforms R3.3 Beta Draft—Cisco Confidential Information • In Service Software Upgrade (ISSU)—Supports a modular-packaging-based release model to minimize impact of upgrades, and supports ISSU with NSF where possible. • Layer 3 Virtual Private Networks (L3VPN)—Supports multiple simultaneous Layer 3 VPN routing and forwarding (VRF) instances.

    Cisco IOS XR Security

    07_1587052717_ch06.qxp 5/15/09 11:21 AM Page 159 CHAPTER 6 Cisco IOS XR Security It is important to control access to the router to prevent unauthorized or malicious use that might take the router offline or use it to launch an attack on the rest of the network. Cisco IOS XR provides the authentication, authorization, and accounting (AAA) frame- work that helps provide secure access via the logical vty and the physical tty ports. Fur- thermore, ensuing sections in this chapter discuss the concepts of task-based authorization and familiarize the user with IOS XR concepts such as admin and SDR planes as well as the uniqueness of user groups and task group configuration. Forwarding plane refers to the components involved in the various stages during packet forwarding. Forwarding plane refers not only to the flow of a packet through the router but also to the packets destined to the router. Protection of forwarding plane is important and necessitates controlling the type of traffic that traverses the router, and limiting the amount of traffic that’s destined to the router itself so that the router does not become a victim of a denial of service (DoS) attack. You might well be familiar with access control lists (ACL) and Unicast Reverse Path Forwarding (uRPF) as popular forwarding plane secu- rity features. Additionally, IOS XR has a concept of Local Packet Transport Service (LPTS). LPTS provides protection against traffic destined to the router. This type of traffic is usually related to routing protocols that typically run on the route processor (RP) of the router, though Telnet, SNMP, NTP, ping, traceroute, and various other services create traf- fic that can be destined to a router’s line card or RP CPU.

    Memory Forensics Analysis of Cisco IOS XR 32 Bits Routers

    Memory forensics analysis of Cisco IOS XR 32 bits routers Abstract Attackers are constantly developing new techniques to bypass current security measures, and they are researching new targets to attack. The "Shadow Brokers" case illustrates that advanced attackers now target network devices such as routers. These core devices handle large amounts of data and are generally not audited by the security team, nor protected by specific security solutions, making them very interesting targets for attackers. This paper explains Cisco IOS XR routers internal, relevant to forensics analysis. As no forensics tool exists on this platform, we develop a tool for dumping the memory of the routers and another one, amnesic-sherpa, to analyze the memory dumps. Also, we demonstrate that by using an automated process based on these tools, we can determine if a router was compromised.
